Question

If an alternator has a flux per pole of \(0.05\ \text{Wb}\), a frequency of \(50\ \text{Hz}\), and \(100\) turns per phase (assume pitch factor and distribution factor is \(1\)), the RMS phase emf is approximately

• A. \(222\ \text{V}\)
• B. \(1110\ \text{V}\)
• C. \(555\ \text{V}\)
• D. \(444\ \text{V}\)

Hint:

For alternators, remember the RMS phase emf formula \(E=4.44f\phi TK_pK_d\).

Answer 1

The Correct Option is B
